The data are simply no reason to reject this fundamental economic precept: When you raise the cost of hiring, companies will do less of it. Until there’s a sound theory for why raising the price of low-skill labor doesn’t lessen employers demand for it, and until that theory is confirmed by serious, empirical analysis based on adequate data, the only legitimate minimum-wage stance is that it shrinks the employment options for the very workers it ostensibly intends to help: the poorest of the low-skilled.
